ABSTRACT:

Background: Intrauterine growth restriction (IUGR) remains as one of the most common complication in females of reproductive age. Untreated individuals may develop condition of infertility initiated by the condition IUGR. Objective(s): Aim of the study is to measure the accuracy of ultra-sonographic determination of TCD/AC vs HC/AC and state more sensitive and specific measure for the determination of IUGR Methodology: For the current study (N=405) pregnant females with gestational age between 18-35 weeks and no congenital anomaly were substituted. All of the samples were obtained after getting informed consent at Hospital . Ultra-sonographic determination of BPD, FL, TCD, AC, HC and EPW were measured and subjected to analysis for the findings. Results: Findings of the study state that among all of the measures determination of ratio of TCD/AC were most significant it shows the area under curve (AUC) to be about 0.911 in case of TCD/AC which is significantly higher as compared to that of HC/AC (0.652). Moreover, specificity and sensitivity of the ratio remained significantly higher for TCD/AC (88%, 69%) respectively as compared to all other gynecological measures. It shows that the best cut-off value of TCD/AC ratio is 14.3%. Conclusion(s):Study concludes on the basis of analysis of the measures obtained from the pregnant females that ratio of TCD/AC was more accurate as compared to the ratio of HC/AC. As signified by the literature the said ratio is far more helpful in the determination of IUGR in early stages in pregnant females. Keywords: Intrauterine growth restriction (IUGR), Trans-cerebellar Diameter (TCD), Femur Length (FL), Biparietal Diameter (BPD).
